1.10.1 Non-MRP Applications
The SMD23E2 and SMD24E2 units have two Ethernet ports with a built-in Ethernet switch connecting the
two. In non-MRP applications, either port can be used to attach the unit to the network. Also, both ports can
be used in non-MRP applications. For example, if two units are located some distance from your controller,
then you need only run one cable from your controller to the first unit. The second unit can then be attached to
the first with a short cable. There is no need to run two cables from your controller.
1.10.2 MRP Applications
In Media Redundancy Protocol applications, the SMD23E2 and SMD24E2 units function as a Media Redun-
dancy Client (MRC). In these applications, both ports are used when wiring the ring, daisy chaining from one
unit in the ring to the next.
1.11 Modbus TCP Connections
The SMD23E2 and SMD24E2 units have two Ethernet ports with a built-in Ethernet switch connecting the
two. Either port can be used to attach the unit to the network. The remaining port can be used to extend the
network to another device if this would reduce wiring costs.
